I have GP4000S on Forte Titans, mount and unmount without tools and I love it. I've had some other combos that were horrible.
The first time with the GP4000S was more difficult, it took a few days to stretch out completely.
I also have to mention that I scored some Aeroplugs and that helped out a bit too.
